556:"The Role of Chunking and Organization in The Process of Recall11The research reported herein was supported through the Cooperative Research Program of the Office of Education, U. S. Department of Health, Education and Welfare; Grant MH11236 from the National Institute of Mental Health, United States Public Health Service; and Grant GN 534.1 from the Office of Science Information Service, National Science Foundation, to the Computer and Information Science Research Center, The Ohio State University."

material. Deaf and hard of hearing students are most likely to have the best experience in class and ease the effects of a split attention if they have a complete view of the classroom. The split-attention effect not only affects a deaf or hard of hearing individual's schoolwork. It affects their daily life as well because visual input is their main source of communication and information about the world around them.

when they direct a learner's attention. In several studies and experiments, Sweller and his associates found that learners had difficulty following some worked examples with diagrams separated from formulas, whereas learners using integrated diagrams were better able to process that information, and significantly improved their performance relative to their peers.
116:
The redundancy effect has also been linked to the split-attention effect. The redundancy effect is the idea that instruction materials that are not integrated properly produce and present information in a repetitive way, making it more likely to process unnecessary information and increase cognitive
77:
Split attention is important evidence of the cognitive load theory as it demonstrates that the working memory load of instructional materials is important in the design of instructional materials. Chandler and
Sweller also found that students viewing integrated instruction spent less time processing

The figure on the left side of the image produces the split-attention effect, while the figure on the right enhances learning because it guides the learner's attention through the worked example. Unincorporated visual displays of information, such as the image above, can be distracting and confusing

and facilitates learning. They found that the split-attention effect is evident when learners are required to split their attention between different sources of information (e.g., text and diagrams). A study done in 1979 by Egan and
Schwartz revealed the importance of chunking in the recall process
81:
Deaf and hard of hearing students often experience and struggle with the visual split-attention effect. Because deaf and hard of hearing students need to focus their attention on the teacher or an interpreter, the student is forced to divide their attention between the instructor and the learning

Consider the graphic below from
Tarmizi and Sweller. They used these graphics to compare the learning that takes place given split attention conditions. Each is a possibility of how one might arrange graphical material within a lesson. Ward and Sweller advise instructional designers to be careful

An auditory split-attention effect can occur when audio material and visual material result in an additional cognitive load. Moreno and Mayer found evidence for auditory split attention when they tested learners with both ambient environmental sounds and music as they learned from instructional

is a learning effect inherent within some poorly designed instructional materials. It is apparent when the same modality (e.g. visual) is used for various types of information within the same display. Users must split their attention between the materials, for example, an image and text, to

There have been propositions to eliminate the term "split-attention effect" and replace it with "spatial contiguity". These phenomena are very similar, however, split-attention conditions do not need to be present in order for the spatial contiguity principle to take effect. The spatial

has been proven to be a successful aid in long-term memory and image recall. Egan and
Schwartz's study also suggests that chunking cannot adequately be implemented when the information and an image produce a split-attention effect.

The split-attention effect is not limited to geometry. Chandler and
Sweller found that this effect extends to a variety of other disciplines, due to it being a limitation in human information processing. This is the result of high visual

Morrison found in another study that integrated materials resulted in higher test scores and reduces extraneous cognitive load.
